More Carbondrive info

Marcel from Universal Transmissions in Germany forwarded us some info about the Gates Carbondrive system for bicycles.

What are the benefits to the Carbon Drive System?

Life – lab testing has shown the Carbon Drive belt to last more than twice the life of chains.
Light Weight – the entire system, 2 sprockets and a belt, weighs less than just a typical chain.

No Stretch – The Carbon Drive belt does not stretch over time like a chain. This means you don’t have to re-tension the belt, or replace the belt due to stretch. This also means no excessive wear on sprockets due to stretch.

Smooth – The instant engagement of the Carbon Drive system gives an unparalleled smoothness that chains can’t meet.

No Noise – The Carbon Drive belt is virtually silent.

No Lubrication – The Carbon Drive belt does not need lubrication to keep it running smooth and silent; this means no grease on your hands, socks or pants.

Open Tooth – the patented open tooth profile of the Carbon Drive sprockets allows mud, dirt, rocks, and other debris to pass right through without a moment of hesitation.

What is the life of the system?

In laboratory testing, the Carbon Drive System lasts more than twice the life of chain. Chains are often replaced due to stretch and wear rather than actual failure. The Carbon Drive belt does not stretch, so the smooth running performance remains consistent throughout its life.

What are the drawbacks of using a Carbon Drive System?Because a belt cannot be broken and then reattached, the Carbon Drive System requires a special or modified frame. A belt also needs center distance adjustment for installation and proper tensioning.  Methods include adjustable dropouts (track forks), eccentric bottom brackets, or eccentric hubs.

How efficient is the system when compared to a chain?Repeated testing has found new belt drives equally efficient to new chain drives, including a third party test evaluating the Carbon Drive system on a bicycle.  Currently, independent testing is being conducted with latest production Carbon Drive components under additional conditions to further confirm the results.

What is the weight of the Carbon Drive system? 

Weights will vary slightly depending on the size of the sprockets and length of the belt.  For example, a Carbon Drive system setup similar to a chain driven 32/19 single speed ratio weighs:

 46 tooth sprocket – 84g , 28 tooth sprocket – 74g , 122 tooth belt – 82g

TOTAL – 240g
